Video transrating in AVC and HEVC transcoding

HEVC (MPEG-H Part 2 and H.265) is a new coding technology which is expected to be deployed on the market along with new video services in the near future. HEVC is a successor of currently widely used AVC (MPEG-4 Part 10 and H.264). In this paper, the quality coding gains obtained for the Cascaded Pixel Domain Transcoder of AVC-coded material to HEVC standard are reported. Extensive experiments ...

Homogeneous Transcoding of HEVC

An Efficient Adaptive Boundary Matching Algorithm for Video Error Concealment

Sending compressed video data in error-prone environments (like the Internet and wireless networks) might cause data degradation. Error concealment techniques try to conceal the received data in the decoder side. In this paper, an adaptive boundary matching algorithm is presented for recovering the damaged motion vectors (MVs). This algorithm uses an outer boundary matching or directional tempo...

A Primer To Video Transcoding: Image Transcoding

In the video transcoding problem, we convert the video from one bit-rate to another which can help us design better streaming servers. This is achieved by changing the resolution as a trade-o for the bit-rate. In this work, we solve a part of the problem. The individual frames are represented in terms of 8 8 DCT blocks. We develop an algorithm for re-sampling the frame in the DCT domain, such t...
